  • Offers a wide range of services
  • Operates nationally and internationally


  • Limited experience and expertise
  • No flexible payment options

Alpha Investigation has been operating for more than 20 years now. Over time, they’ve developed a wide range of services for their clients. 

With their decades-long experience, they’ve also successfully established connections not only across Australia but also around the world. 

With international backing, Alpha offers reliable investigation services to its clients. 

One of their popular services is their surveillance service for cheating partners. 

They deploy investigators who can discreetly follow an individual for an entire day. We also note that they make sure to use ethical ways of gathering evidence.  

They operate 24/7, making their services more accessible and available. 

For us, this also gives clients peace of mind, as they can easily ask for updates on their investigation at any time. 

Although they advertise themselves as experts in many areas, we think their experience is limited to basic investigations. 

We noticed that they repetitively take on surveillance requests and fail to explore the many services they offer. 

Nevertheless, we appreciate that they offer affordable rates, which can sometimes depend on the complexity of the client’s request. 

They also provide a free initial consultation to their clients. 

However, they do require upfront payment, and they also don’t offer flexible payment options. 

2. BPI Private Investigators Perth

  • Specializes in bug sweeping
  • Accredited in Technical Surveillance Countermeasures


  • Limited services offered
  • Limited experience and expertise

Private Investigation covers different situations that require different skills. One of these is bug sweeping. 

Bug sweeping is sometimes called debugging. It refers to surveillance done to spot illicit electronic surveillance such as unwanted bugging and eavesdropping.

If this is the exact service you need, then we just found you your guy.   

Budget Private is the leading bug sweeper in Perth, and they are, in fact, accredited in Technical Surveillance Countermeasures. 

We love that they’re transparent about the equipment they use for this task. We think this gives clients confidence in their surveillance services. 

They also make sure to explain to their clients how bug detection works and advise them when it’s time to contact a bug sweeper.

However, while their focus on bug sweeping makes them the best at it, we think it also limits the services they offer. It also tells us that they’re not well-experienced in other areas of private investigation. 

In any case, they’re open 24/7 and offer a free quote to their clients. 

True to their advocacy for discreet, low-cost, and quality services, they provide their services at an affordable price.

3. Affordable Private Investigators

  • Offers a wide range of services
  • Has international connections


  • Has no physical address

As ex-detectives of the Western Australia Police Force, the agents of Affordable Private are fully equipped with the necessary training and experience for investigation.

Established in 1992, this company of former police officers is one of the longest-running private investigation agencies in Perth. 

They offer a wide range of services including those that are unique to them. These include civil and family court investigations.  

Additionally, the company’s founder once worked as an insurance broker, so the company also takes on investigations of insurance fraud.

We’re also interested in their internet scam investigation services. We think this is timely especially since most frauds happen online these days. 

They have a high success rate, a WA license, and an indemnity insurance policy to assure clients of their credibility and integrity.

They’re open 24/7 and offer a free initial consultation too.

Their consultation includes an outline of the process, the timeframe of investigation, and estimates of cost. As their name suggests, they try to accommodate all clients regardless of their budget.

Unfortunately, for a big agency, they don’t have a physical address, which can be troublesome for clients who prefer to discuss sensitive and confidential matters in person. 

4. Mercury Investigative Services

  • Specializes in skiptracing
  • Offers a wide range of services
  • Clients can opt for flexible and convenient payment methods


  • Requires immediate and upfront payment from their clients

With over 100 agents, Mercury Investigative is one of the biggest private investigators in Perth. They cover various investigation requests, ranging from simple surveillance to delicate child custody investigations.

They’re popular for their skiptracing service. Skiptracing is essentially the process of locating a person’s whereabouts.  

This service makes them the best at handling missing person cases or even debt collection cases. 

With over two decades of experience, Mercury Investigative is confident in requiring upfront payment from its clients. 

If you think you’d need their services again, you can opt to be retained as their client upon payment of the retainer fee. 

This fee doesn’t include the actual investigation services that they do. They might also require immediate payment for these services even when results haven’t been yielded yet. 

We think this can cause some hesitation on the part of the client, considering that they’ve yet to see if the investigation is efficient enough to yield results. 

In any case, they offer flexible and convenient payment options including payment through their website. Once payment has been made, they start investigating their clients’ requests. 

They’re available 24/7 and offer free consultations as well.  

5. Mick Buckley Private Investigator

  • Offers a wide range of services
  • Serves almost all of Australia


  • Charges for face-to-face consultation
  • They don’t charge a fixed price

Having been in business for over 30 years, Mick Buckley is the most experienced on our list. 

This one-man team started his career in the police force and was later invited to join the Criminal Investigation Branch (CIB). 

He was involved in numerous high-profile cases, which earned him expertise in doing background checks, skip tracing, and many more. 

Although he’s trained to handle high-profile cases, we love that he doesn’t hesitate to take on what others would consider a small job. 

Over time, he successfully hired several agents to carry on his business. And today, they offer all kinds of investigation services including infidelity, missing persons, surveillance, bug sweeping, and stolen pet cases. 

No job is too small for Mick Buckley, and clients love him for this. 

They’re also open 24 hours, so clients can ask for updates on their requests any time they want.  

We also appreciate that they offer a free initial consultation.

However, they charge a fee if you request an in-person consultation. 

This might discourage people who need an in-depth consultation but are still undecided about whether to hire a private investigator or not.

They don’t charge a fixed price, so they opted to dedicate an entire page on their website explaining how they charge their clients.

For example, when doing surveillance, they count the hours dedicated, the operatives needed, and the kilometers covered by the investigation. In this sense, they can be pricey considering the uncertainty of the investigation process.

They are, however, always transparent about their charges.
